Imaging the Core of Fukushima Reactor with Muons
MUON TOMOGRAPHY IMAGING THE CORE OF FUKUSHIMA REACTOR WITH MUONS The 9.0-magnitude earthquake, followed by the vast tsunami on March 11, 2011, caused a nuclear crisis at the Fukushima Daiichi reactors. Damage of the reactor cores attracted worldwide attention to the issue of the fundamental safety of nuclear energy. The Japanese government announced a cold shutdown in December 2011, and began a new phase of cleanup and decommissioning. However, it is difficult to plan the dismantling of the reactors without a used experiments and modeling to show how muon imaging with de- realistic estimate of the extent of the damage to the cores and knowl- tectors external to the reactors can enable damage assessment inside edge of the location of the melted fuel. Access to the reactor buildings Fukushima. Physical Review Letters, AIP Advances, and the Journal of is very limited due to high radiation fields. Los Alamos researchers have Applied Physics have published different aspects of this work. Image from “Los Alamos, Toshiba probing Fukushima with cosmic rays,” Los Alamos National Laboratory YouTube video. Muon imaging offers the potential to image the nuclear reactor cores with- out access to the cores. The method utilizes naturally occurring cosmic-ray muons to image dense objects. There are two types of muon imaging: transmission and scattering. In practical applications, muon transmission imaging often suffers from poor position resolution due to the continuous scattering along the muon path, and from poor signal-to-noise ratio due to the small detection area (typically on the order of 2 m2). In addition, calcu- lating transmission requires precise knowledge the incident muon flux that can be difficult to estimate.

These constraints is a smaller but high value niche market servicing the need to be adapted to match requirements for object and requirements for border security, and cargo and vehicle material discrimination, throughput, reliability, safety and inspection (CVI). This latter application requires higher size. There are currently three main technologies used for X-ray energies of up to 10 MeV using an electron linear security systems which are characterised by their accelerator (linac) source to penetrate fully loaded penetration in steel, in Fig. 1. shipping containers. Increasingly, methods are required to improve throughput and provide a higher level of material discrimination during inspection. This paper will briefly review the elements required to make an effective X-ray source, whilst outlining the RF technology required to drive a linac-based X-ray security system.

Eyes the Next Big Collider by Elizabeth Clements
Industry eyes the next big collider by Elizabeth Clements Technology developed for the symmetry | volume 04 issue 05 jun/jul 07 International Linear Collider could help make nuclear waste safer, cargo inspection easier, and drug design more effective. 23 With a blue marker poised at a large white flip chart, Maury Tigner, a physicist at Cornell University, turned to a group of about 10 representatives from industry and asked, “What kind of applications interest your com- pany?” The room was cramped and beige, a generic hotel meeting space, strewn with coffee mugs and crinkled candy wrappers. The setting gave no hint that the discussants were forming a cutting-edge technological vision. Bill Umbenhaur of Everson Tesla wanted to know more about long-term medical applications. Dean Hoffman of Sciaky was interested in general lab services and machines. Karen Kimball of Parsons described her company’s interest in design and construction management. In other rooms around the hotel, similar groups were also brainstorming. Each was envisioning how components being developed for the International Linear Collider (ILC) could lead to spin-off applications and technologies. Before the day was out, the group would come up with ideas for decon- taminating nuclear waste to make it safer to store, inspecting cargo reliably and rapidly at ports around the world, and performing liposuction by laser. 24 Imagining potential Charged with thinking outside the box and fueled with caffeine and sugar, about 40 ILC scientists and people from industry participated in the ILC Technical Applications Workshop on May 15 in Dulles, Virginia. Ken Olsen, president of the 31-member Linear Collider Forum of America, arranged for the industry leaders to attend.

CIEMAT, Av. Complutense 40, 28040, Madrid Spain *email: [email protected] Abstract In homeland security, neutron detection is used to prevent the smuggling of Special Nuclear Materials. Thermal neutrons are normally detected with 3He proportional counters, in the Radiation Portal Monitors, RPMs, however due to the 3He shortage new procedures are being studied. In this work Monte Carlo methods, using the MCNP6 code, have been used to study the neutron detection features of a 10B+ZnS(Ag) under real conditions inside of a RPM. The performance for neutron detection was carried out for 252Cf, 238U and 239Pu under different conditions. In order to mimic an actual situation occurring at border areas, a sample of SNM sited inside a vehicle was simulated and the RPM with 10B+ZnS(Ag) response was calculated. At 200 cm the 10B+ZnS(Ag) on RPM response is close to 2.5 cps-ng 252Cf, when the 252Cf neutron source is shielded with 0.5 cm-thick lead and 2.5 cm-thick polyethylene fulfilling the ANSI recommendations.

Detection of Nuclear Weapons and Materials: Science, Technologies, Observations
Detection of Nuclear Weapons and Materials: Science, Technologies, Observations Jonathan Medalia Specialist in Nuclear Weapons Policy June 4, 2010 Congressional Research Service 7-5700 www.crs.gov R40154 CRS Report for Congress Prepared for Members and Committees of Congress Detection of Nuclear Weapons and Materials: Science, Technologies, Observations Summary Detection of nuclear weapons and special nuclear material (SNM, plutonium, and certain types of uranium) is crucial to thwarting nuclear proliferation and terrorism and to securing weapons and materials worldwide. Congress has funded a portfolio of detection R&D and acquisition programs, and has mandated inspection at foreign ports of all U.S.-bound cargo containers using two types of detection equipment. Nuclear weapons contain SNM, which produces suspect signatures that can be detected. It emits radiation, notably gamma rays (high-energy photons) and neutrons. SNM is dense, so it produces a bright image on a radiograph (a picture like a medical x-ray) when x-rays or gamma rays are beamed through a container in which it is hidden. Using lead or other shielding to attenuate gamma rays would make that image larger. Nuclear weapons produce detectable signatures, such as radiation or a noticeable image on a radiograph. Other detection techniques are also available. Nine technologies illustrate the detection portfolio: (1) A new scintillator material to improve detector performance and lower cost. This project was terminated in January 2010. (2) GADRAS, an application using multiple algorithms to determine the materials in a container by analyzing gamma-ray spectra. If materials are the “eyes and ears” of detectors, algorithms are the “brains.” (3) A project to simulate large numbers of experiments to improve detection system performance.

The facility was carried out for an extensive range of values for the collimator ratio L/D, the main parameter which describes the quality of the produced radiographic images. The results show that the presented facility provides high thermal neutron flux; while with the use of single sapphire filter fulfills all the suggested values which characterize a high quality thermal neutron radiography system. A comparison with other similar facilities indicates that the use of a photoneutron source using a 10 MeV electrons beam is a useful substitutional for radiographic purposes.

Moreover, its application allows to obtain different responses to neutrons depending on their energy spectrum. This is achieved because the material, firstly, has high content of Gd, which absorbs neutrons with following emission of γ-quanta, and, secondly, detects this radiation efficiently thanks to high stopping power, fast scintillation kinetics, high scintillation light yield and good energy resolution. It was shown by simulation that several characteristic regions could be distinguished in γ-quanta pulse height spectra acquired with GAGG:Ce crystal under neutron irradiation, with energies nearly 90 and 190, and 511 keV; all these lines have different relative intensities depending on incident neutrons kinetic energy. This was confirmed by followed measurements with Am-Be neutron source. Scintillator shows coincidence time resolution better than 200ps for γ-quanta of 511 keV energy, what makes it the material of choice to separate neutrons by time-of-flight technique.
